Camco's RV RhinoFLEX 15' Sewer Hose Kit with RhinoFlex Hose and Swivel Fittings features a super tough bayonet fitting with four prongs for a more secure fit. At the dump-station end we've added an easily detachable 4-in-1 translucent elbow adapter for fitting to 3 in. slip or 3 in., 3-1/2 in. and 4 in. threaded pipes. It's a ready-to-use kit made with 23 mils of the toughest hose you can buy. It includes a bayonet and elbow storage cap. The kit compresses to 56 in. for storage and the removable 4-in-1 adapter allows you to store the hose in 4 in. square bumpers.
